Detailed Description

Task stack initialization, allocation and free functions.

Initialize the task stack allocator with bsp_stack_initialize(). To enable the task stack allocator use the following in the system configuration:

#include <bsp/stackalloc.h>
 
#define CONFIGURE_INIT
 
#include <confdefs.h>

Task stack allocator for CONFIGURE_TASK_STACK_ALLOCATOR.

In case the designated task stack space from bsp_stack_initialize() is completely in use the work space will be used to allocate the stack.
